Plastic ball bearings to fit shaft sizes from 3mm up to 30mm
These plastic ball bearings have acetal (POM-C) rings and nylon (PA66) cages. They are supplied from our UK stock and are corrosion resistant, non-magnetic, non-conductive and much lighter than steel bearings. We can supply plastic bearings in alternative materials for greater corrosion resistance or extreme temperatures. See Bearing Materials for more information on plastic grades. For higher loads, we offer ceramic bearings in zirconia or silicon nitride.
Plastic bearings are semi-precision. The bearings below are open but may also be supplied with plastic shields on request. Plastic is more prone to temperature induced expansion and contraction.
See Products Variants below for flanged plastic bearings.
